Remote Access Point Discovery Guidelines
The following guidelines apply to the discovery of remote access points:
•
Enable SNMP and SSH on all standalone access points.
•
Unblock the following ports in the firewall at the site where the wireless controller is
located so that the remote access points can communicate with the wireless controller:
-
For models WC7600 and WC9500:
•
TCP port 22. Used by Secure Shell (SSH) and Secure Copy (SCP) for the
transfer of software images and large configuration files and for the transfer over
a tunnel.
•
UDP port 69. Used by TFTP for software image upgrades of standalone access
points.
•
UDP port 123. Used by Network Time Protocol (NTP).
•
UDP port 138. Used by NetBIOS to resolve names.
•
UDP port 161. Used by the SNMP discovery process.
•
UDP port 6650. Used by the control channel between the wireless controller and
the remote access point.
•
UDP port 7890. Used by the multicast discovery process. This port does not need
to be unblocked in a configuration in which remote access points are located
behind a NAT router.

For models WC7500 and WC7600v2:
•
TCP port 22. Used by Secure Shell (SSH) and Secure Copy (SCP) for the
transfer of software images and large configuration files and for the transfer over
a tunnel.
•
TCP port 6670. Used for communication and backward compatibility with access
points that run an older firmware release.
•
TCP port 6680. Used for communication and backward compatibility with access
points that run an older firmware release.
•
UDP port 69. Used by TFTP for software image upgrades of standalone access
points.
•
UDP port 123. Used by Network Time Protocol (NTP).
•
UDP port 138. Used by NetBIOS datagram service.
•
UDP port 161. Used by the SNMP discovery process.
•
UDP port 6650. Used by the control channel between the wireless controller and
the remote access point.
•
UDP port 7000. Used for Layer 3 roaming support.
•
UDP port 7890. Used by the multicast discovery process. This port does not need
to be unblocked in a configuration in which remote access points are located
behind a NAT router.
